EMMONS M. PARKHURST, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE CHAMPION SHOE BURNISHING MACHINE COMPANY.

BURNISHENG=MACHlNE FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 353,756, dated December 7, 1886.

Application filed January 2, 1886. Serial No. 187,322.

To all whom it may concern.-

Be it known that I, EMMONS M. PARK- HURST, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Burnishiug-lliachines for Boots or Shoes, of which the following is a specification.

My invention has reference to a burnishingmachine for boots and shoes; and it consists in certain improvements, fully set out in the accompanying drawings, which form part thereof.

My object is to providea burnishing-machine with a blunt V-shaped burnisher, formed substantially as shown, whereby a pointed part may be obtained to enable the burnishing of the smallest as well as the largest of shoes.

My object is also to so construct the machine that the boot or shoe is pressed upward against the burnisher and the upward thrust thereon is received by suitable anti-friction guide-rollers or their equivalents.

In the drawings, Figure l is a plan view of aburnishing-machiue embodying my improvements. Fig. 3 is a perspective view of the burnisher removed from the machine. Fig. 4 is a crosssection on line 00 a: of the burnisher, and Fig.

5 is a perspective view of the crank-head.

A is the frame of the machine. Bis the crank-shaft, and is journaled therein. 0 is a band-wheel secured to said shaft, and D is the 5 crank-head, which is provided with T-shaped slot 01 across its face. Adjustably secured in said slot (1 is the crank-pin E. This crankpin is connected by a link, F, with the reciprocating guide-shaft G, working through the 0 bearing H, and carrying upon its outer end the burnisher-frame l, in which the burnisher J is secured.

The burnisher-frame is provided with guides K on its side, and preferably over the connections with the burnisher. These guides K work against the anti-friction rollers L, journaled on stationary bearings secured to the brackets M, which brackets are bolted to the main'i'rame of the machine. As the burnisher is reciprocated the upward thrust, due to the and this burnisher is made blunt V-shaped,

pressure of the shoe or boot, is received by the rollers and prevented from coming upon the guide shaft G, preventing it wearing upon its bearing and binding. N is a gas pipe from which a number of small gas-jets burn, the flames projecting toward the rear or enlarged part, 0, of the burnisher to keep it at, uniform temperature.

The burnisher is shown in perspective in Fig. 3, and in section in Fig. 4, from which figures its shape may be deduced. In crosssection it consists of the enlarged or semicircular back ptrtior, O, and the forward or edge portion, P, connected by the flattened sides it,

6 so as to provide the point Q, by which it may 5 enter the smallest recesses or curves, and thus be suitable for large as well as small boots or shoes.

It is necessary in cases when shoes and slippers are made with galloon or English channel finish to provide the small rounded portion g on the front or pointed edge, Q, of the burnisher, and said portion q is provided with a guide-edge, q, against which the outer edge of the sole is placed to guide the sole, so that its under surface close to the edge may be burnished. If the guide edge or projection g were not used, there would be liability of the shoe slipping to one side and the round portion g burnishing that portion of the sole required to be with a'dead finish, and again, it reduces the care required by the operator, and thereby facilitates the work, increasing the production. Besides the above, the juncture 85 of the parts q q forms a clean corner, which gives to the lower edge of the sole a highlyfinished appearance.

It is immaterial to my invention what particular construction of a crank or crank-pin is provided so long as the throw of the crank is made adjustable. For instance, in place of the crank-pin working in the T-shaped slot of the crankhead and being bound therein by a nut, a screw (indicated on dotted lines) may be provided to move said crank-pin nearer or farther from the center of the shaft. Neither (101 limit myself to the particular construction of burnisher-frame and its connection with the crank-head.- Therefore, while I rco 3. The burnisher .T, made blunt V shape,

and having its rear edge thick, as at O, and r5 forward edge sharp, as at P, and provided with the curved part q and guide part q, substan tially as and for the purpose specified.
